Oseltamivir (Tamiflu)
Brands Names: Tamiflu
- Form of administration: Capsule or syrup
-
Why is the drug here:
This is the only anti-viral we have for treating the flu (influenza virus, it is theoretically effective against both influenza A and influenza B.
-
Purpose of treatment:
To shorten the number of recovery days from influenza. This medication achieved fame in 2009, when the outbreak of swine flu gave the world a big scare (and rightfully so). Ever since, several studies questioning the efficacy of Tamiflu have been conducted. However, the guidelines set by the majority of health organizations around the world have not changed.
The Centers for Disease Control and Prevention (CDC) supports the use of Tamiflu for any patient with suspected or confirmed Infuenza who is hospitalized, has severe or complicated illness or is at higher risk for influenza complications.
Therefore, if you or your child do not fall into one of the above categories and your caretaker has prescribed you with Tamiflu, he/she better have a good reason for why they did so.
- Ingredients: The active ingredient Oseltamivir, which interferes with the spread of the virus in the body.
-
How to use:
Tamiflu capsule can be swallowed whole with water. For children who are unable to swallow whole capsules, the capsule can be broken, and the inside parts taken with a drink or pudding. The appropriate dose for adults with renal failure is 75 mg, twice daily for 5 days. Patients who are immune suppressed are often prescribed the medication for as long as 10 days. In children, the correct dosage varies depending on age and weight, but I will not elaborate on dosing in children as its use in those who are not hospitalized is quite rare.
-
Benefits:
This is probably the only drug that can slightly shorten recovery time from influenza, especially if it is started soon after the first symptoms appear. According to recent studies, the efficacy of the drug, if it all present, is very limited.
-
Side Effects:
These include vomiting and diarrhea. This medication is renally cleared and therefore dose reduction is advised for people with renal impairment. .

Another word from the doctor:
If you are one of those people who have or are hoarding this medication thinking this is what is going to save you when you get influenza – you are deeply mistaken.
If you are one of those people who pop a Tamiflu capsule every time you get a viral infection – you are in trouble.
If your primary care physician or pediatrician prescribed you or your healthy child Tamiflu – you have a problem.
If you receive your flu shot every year, despite its limited efficacy– you are a champ!
